VThisinvention relates to a combination tool for a firearm, moreparticularly to a tool for cleaning the chamber of the firearm.

Adequate cleaning of the chamber of a firearm is usually a diflicultprocedure and is especially true of l firearms having receivers of suchshape. as to obstruct free access to the bore. When the,

Referring to Fig. 1, there is: shown in its preof securing the cleaningbrush to the combination tool: 1

Fig. 4 is a partial bottom view of Fig. 2 taken opposite the plane, 4.-4showing the ruptured cartridge case extractor groove. Fig. .5 is a rightend elevational ferred form a. combination tool in assembled rela tion.A handle I is preferably formed from a cylindrical bar. One end ofhandle I has an inchamber is not readily accessible from the breech Iend,'it is necessary to improvise some sort of cleaning implement forscouring the chamber, as a suitably formed offset cleaning rod. Formilitary us such an improvised cleaning toolwould be decidedlyinconvenient to carry separately in the field. As it is imperativethat arifle bore and chamber be kept clean at all times, particularly thechamber, it is highly desirable to carryclean ing implements with therifle.

arm, access to this recess being made thru a trap door in the buttplate. Occasionally it is desirable to disassemble the entire rifle fora thorough cleaning and infrequently to replace a damaged or defectivepart. This procedure is facilitated by a screw-driver and a drift pin. Aruptured cartridge case in the chamber is best removed with aspecialextracting tool. If these various tools are carried separately some willundoubtedly be lost or misplaced andhence will not be available whenmost urgently needed. Therefore a, tool which combines the several toolsin one, which can be conveniently carried within the buttstock of thefirearm, and is convenient to Accordingly it is an object of thisinvention to provide a compact combination toolwhich combines implementsfor cleaning the. chamber of the firearm and for disassembling thefirearm. 1 1

A particular object of this invention is to provide a combinationtoolincorporating therein an extractor removing tool for removal of theextractor from the bolt of a rifle such as disclosed in U. S. Patent No.1,892,141 to John C. Garand.

The specific nature of the invention as well as other objects andadvantages thereof will clearly appear from a description of a preferredembodthe accompanying drawing, in which: 7

Fig. 1 is a top elevational view of a combina- -tion tool shownpartially in section.

This is usually accomplished by inserting these implements in. asuitable recess within the butt-stock of the fire- I tegrally formedhead Ia. Two fork-like prongs 2a and 2b (Fig. 5) project; upwardlyfromthe end of head la. These prongs are for removing the extractor fromthe bolt of a rifle such as disclosed in the aforementioned U. S. PatentNo. A suitable recess. 3 is provided on the head Ia between the prongsiaa nd2b to hold an ejector (not shown) in position while .the lower. edgeof the face and opposite the prongs 2a and 2b, a narrow milled slot 4(Fig. 4) is provided. This slot is semi-circular in depth and fits thebase ,of a cartridge. The lower side lc of head Ia opposite the prongs2a and 2b is milled flat and a. semi-circular opening 5 (Fig. 4) smallerin diameter than the slot 4 in order to fit the extractor groove of acartridge case, is provided from the flat side l-c to the slot 4. Justto the rear of thesurface lc axclear'ance cut 6 is provided in the headla to allow the tool to be inserted within the receiver (not shown) of arifle similar to that shown in U. S. Patent No. 1,892,- 141toengage andextract a ruptured cartridge case. i 1

Adjacent the head la two flat milled. surfaces 10, and 112 (Fig. 2)diametrically opposed, are

provided on the handle I. These surfaces ar in l the same horizontalplane as the slot 4. A centrally located transverse hole 8 is providedin thehandle I approximately in the center of the surfaces 1a andflb.Arivet 9 inserted. in the hole 8 fastens a blade 10 securely but movablyabout the axis of the rivet 9 to the handle 6. The blade ID has aflatoutwardly projecting boss i 0a which bears against the surface 1b. Oneend Illa of blade I0 is shaped .toform a conventional screwdriver bladewhile the other end Illb forms a sion rod l2 has an integrally formedshort tubular Fig. 2 is a longitudinal sectional view taken 3 along thecentral longitudinal axis of Fig. '1. i

Fig. 3 is a cross sectional view taken along the plane 3-3 of Fig. 2showing a preferred method head I2a projecting outwardly from the handleTwo displaced holes 13a and |3b are provided in the rod and areconnected by aslot M. A

spring clip I5 slidably surrounds. the handle I.

view taken is brought The clip l has an integral spring arm l5aextending along the handle I, the end of which is slightly upturned. Apin I6 having an integral shoulder Illa is riveted or otherwise securedto the arm Ida and projects downwardly thru a hole I I (Fig. 2) in thehandle I into the hole I3a in iii.

the rod I2. A detent I51) provided on-the' clip lily engages acorresponding notch I8 in the handle I after the pin I6 has beeninserted in the hole I1 and the clip I5 pushed slightly to the rear .so'

that the smaller diameter of pin I6 engages the rear edge of hole I 1.

Thus when the upturned end of the spring arm I5a is lifted upwardly theI shoulder I6a on pin I6 will bear against the'unto a position where theshoulder IBa is aligned with the hole "in the handle I. -A suitablecleaning brush I9 is movably secured to the end I2a' of the rod Izbyapin 20 which is inserted in suitable holes 2| and 22 in. the end I2aand thru the hole I9a of the brush I9. is secured to the end IZa by thering spring 23 The pin 20 which surrounds the member I200. The spring 23l is secured to the pin by any suitable means,

as by riveting. The hole I9a thru the end I!!!) of brush I9 is coneshaped at each end to permit angular motion of the brush I9. While thebrush I9 is preferably attached to the U-shaped member in the mannershown, the brush may be attached to this member by any suitableconventional toggle or universal joint means.

To use the combination tool for cleaning the chamber of a rifle theextension rod I 2 is first extended by lifting the pin I6 out of thehole I3o by raising the spring I5a and withdrawing rod l2 from theholeIIuntil the pin It strikes a shoulder I on rod I2 at the rearo'fhole I3b'. The pin I6 is then allowed to enter the hole I3b therebylocking the rod I2 to the handle I. With the tool thus extended thebrush I9 is readily inserted into the cleared chamber of a firearm.

As the brush I is attached to the handle I by a toggle joint thehandle'can be bent at a considerable angle to clear any obstructingportion of the receiver. For the best scouring action the handle shouldbe revolved, such revolving motion being imparted to the brush by thetoggle joint even though the handle may not be parallel to the chamber.The tool is most conveniently rotated when the blade It! is pivoted to atransverse position with respect to the body of the tool. The blade II)in such position facilitates grasping of the. tool and permits a readyapplication of a revolving motion.

A ruptured cartridge case'may be iextracted from the chamber after thebolt is withdrawn vby holding the tool in ;a vertical-position andsliding the head Ia of the tool over the head of a cartridge (not shown)so that the slot 4 engages the rim of the cartridge. Using the bridge ofa receiver (not shown) as a fulcrum and the handle I as a lever theruptured case is readily removed when pressure is exerted against thehandle. The screwdriver Illa and drift pin IlJb may be used in aconventional manner, the handle I also serving as a handle for thescrewdriver when the blade I0 is turned at an angle to the handle, aboutthe pin-'9. f I

The extension rod I2 of this tool is provided to give extra length tothe tool so that when used "for cleaning the chamber of a rifle thehandle I will project beyond the breech mechanism (not shown), therebyeliminating the danger of injury to the user by keeping the hand awayfrom contact with any metal projections of the breech.

The combination tool is however conveniently carried within a suitablerecess in the buttstock of a rifle (not shown) when the rod I2 is in thefully inserted position as shown in Fig. 2 and the blade I0 isturnedparallel to the handle. I. Thus the tool becomes a compact combinationof useful cleaning and disassembly implements which are not easily lostand which may be carried with the rifle with no inconvenience andbe'ready' fo'r use at all times.
